ATTACHMENT FOR BOTTLING-MACHINES.

Specification of Letters Patent.

Patented Sept. 24:, 1912.

Application filed March 1, 1910. Serial No. 546,674.

To all whom it may concern:

Be it known that I, ARTHUR F. A'rwoon, a citizen of the United States,residing at Attleboro, in the county of Bristol and State ofMassachusetts, have invented new and useful Improvements in Attachmentsfor Bottling-Machines, of which the following is a specification.

This invention relates to attachments for capping machines, corkingmachines, filling machines, or combined filling and stoppering machines,etc.

It is well known, during the operation of filling bottles with machinesof this kind and with the contents above stated that bottles havingflaws burst from the pressure of the gas with the result. that theflying fragments of glass frequently injure the operator.

The present invention, therefore, has for one of its objects theprovision of a construction including a plurality of movable screensarranged to flank the bottle receiving space of a bottling machine andseal the said space during the operation of filling a bottle, so that inthe event of the bottle bursting the fragments of glass will beprevented by the screens from flying outwardly and into the face of theoperator.

Another object is the provision of a construction whereby the screensare automatically operated to unseal the bottle receiving space when thefilling head is in raised or inoperative position and automatically sealthe said bottle receiving space when the filling head bears on the neckof the bottle, or in other words, is in filling position.

it-h these and other objects in view, which will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings and more particularly pointedout in the appended claims, it being understood that various changes inthe form, proportion, size and minor details of the device may be made,within the scope of the appended claims, without departing from thespirit or sacrificing any of the advantages of the in vention.

- In the accompanying drawings, forming a part of the specification:Figure 1 is a side el vation of the device applied to a well-known formof bottling machine, and showing the parts in closed position. Fig.

2 is a similar view but showing the parts in open position. Fig. 3 is afront elevation of the device with a portion of the front guide of themachine broken away. Fig. at is a rear end elevation. Fig. 5 is a detailperspective of the screen operating mechanism.

, Fig. 6 is a similar view of the member con necting the screenoperating mechanism with the filling head. Fig. 7 is a detail sideelevation of the screen shown on the right in Fig. 3. Fig. 7 is a topplan view of the same. Fig. 8 is a side elevation of the gate shown onthe left in Fig. 3. Fig. 8 is a plan view of the same. Fig. 9 is adetail perspective of the front screen.

Similar numerals of reference are employed to designate correspondingparts throughout.

The machine to which my device is applied may be of any well-knownconstruc tion. For purposes of illustration, however, I have elected toshow a machine provided with a reciprocating filling head located at theupper end of a bottle receiving space. Reference to Figs. 1 and 4:inclusive discloses the fact that the bottle holding frame and the headthe only parts of this machine illustrated, it being unnecessary to showthe supporting base wherein a treadle, connected with the filling head,is employed to reciprocate the said filling head.

The bottle holding platform or table is designated by the numeral 5.This member is arranged on the upper end of the supporting base (notshown), and adjacent to either end and in alinement with itslongitudinal central portion is provided with a pair of verticallyextending hollow cylinders 6 and 7 These members rise to any convenientheight and receive a pair of guide rods 8 and 9, the lower ends of thelatter being connected in any suitable manner to the foot treadle (notshown). The guides 8 and 9 slidingly fit in the cylinders.

The cross bar of the filling head is designated'by the numeral 10, andcorresponds in length to the length of the table 5 and adjacent to itsopposite ends with suitable openings for the reception of the shoulderedend portions of the guide rods 8 and 9. The extremities of the guiderods 8 and 9 extend above the upper face of the cross bar 10 and arescrew-threaded for the reception of nuts 11 and 12, by means of whichthecross bar is secured to the guide rods 8 and 9.

The filling head is designated in general by the numeral 13 and issecurely fitted in a central opening formed in the center of the crossbar 10, its lower end portion depending below the lower face of thecross bar and being provided with a lateral opening 14 for the receptionof a pipe leading from the source of supply. The device forming aportion of the subject matter of the present invention is connected tothe cylinder 7 at the rear end of the table 5 and is further connectedwith the cross bar 10, in such manner that the cross bar 10 upon beingreciprocated in the manner before described, will likewise reciprocatethe parts about to be described.

Fixedly secured to the lower end portion of the rear end cylinder 7 is acollar 15 and extending rearwardly from this collar and arranged atright angles to the cylinder 7 and parallel with the longitudinal planeof the table 5 is a cylindrical arm 16. Rising from the inner endportion of the arm 16 is aright angular-shaped bracket the sides ofwhich are designated by the numerals 17 and 18. The vertical arms 17 ofthis bracket rises to a point in a plane with the upper end of thecylinder 7 while the inner end of the horizontal side 18 is integrallyprovided with a cap 19 having an opening in axial alinement with theaxis of the collar 15 and adapted to bear upon the upper end of thecylinder '7 and receive the rear guide rod 9. The horizontal side 18extends rearwardly. The rear portion of the horizontal side 18 isprovided with an elongated slot extending longitudinally from the rearend of the side, and rising from the inner end portion of said slot andlocated on the opposite sides of the said slot are cheek plates 20 and21, the function of which will appear later.

Arranged to slide upon the arm 16 is a sleeve 22. This member isconsiderably less in length than the length of the arm and rising fromits inner end is a yoke, the arms 23 and 24 of which straddle and extendconsiderably above the horizontal side 18 of the bracket. Fulcrumedbetween the cheek plates 20 and 21 is a lever. This lever is of peculiarconstruction having arms 25 and 26 arranged at substantial right anglesto each other and unequal in length. The longer arm 26 is arrangedbetween the cheek plates 20 and 21 and is provided at a point adjacentits juncture with the short arm 25, with an opening which receives a pin27 passing through alining openings in the cheek plates. The longer arm,as shown in figure 2 extends downwardly and rearwardly and adjacent toits lower end is bent downwardly, as shown at 28, the said downwardlybent portion extending to a point adjacent to the sleeve 22 and providedwith a recess in which is mounted a bearing roller 29. Rising from theupper side of the sleeve 22 and between the outer end of the latter andthe yoke is i a vertical guide extension 30. The guide extension 30 isconsiderably less in height than the yoke and its forward side or thatadjacent to the yoke bears on the bearing roller 29. Owing to thedisposition of the lever, it is evident when its short arm, whichextends substantially vertical, is moved, that the sleeve and yoke willslide on the arm 16, it being understood that when the sleeve movesoutwardly the bearing roller 29 will engage with the extension 30 andwhen moving inwardly, the said bearing roller will engage with a similarguide extension 31 arranged between the arms of the yoke, as clearlyshown in Figs. 1 and 2, both arm extensions forming a suitable guide forthe bearing roller 29.

In order to reciprocate the sleeve upon 1 the arm 16 simultaneous withthe reciprocation of the filling head'and cross bar, the followingconstruction is employed :-By reference now to Figs. 1, 2 and 5, it willbe seen that connection between the cross bar and short arms 25 of thelever is established by means of a connecting rod designated in generalby the numeral 32. This member is provided at one end with a housingincluding a bottom wall 33, side walls 34 and 35, and a top wall 36.This housing is likewise provided with a rear wall which may be formedintegral or otherwise secured to the forward end of the arm 32 as shownin the drawings. With this construction, it will be evident that thefront of the housing will be open and by virtue of the distance betweenthe top and bottom and side walls an opening will be presentedsufiiciently large to receive the rear end of the cross bar 10. Thebottom 33 and top 36 are provided with alining openings which alinewiththe opening in the rear end of the cross bar and receive the upperend portion of the rear guide rod 9. VJith this construction, it will beevident that the connecting rod is fixedly secured to the cross bar.

It might here be stated when the sleeve 22 is moved inwardly and bearson the lower end of the bracket that the short arm 25 of the lever willextend substantially horizontal and its lower side will be in ahorizontal plane, or substantially so with the upper face of theconnecting rod 32, as clearly shown in Fig. 1. It will be seen now byreference to Figs. 1 to 3 inclusive that the rear or free end of theconnecting rod is provided with a slot 37 extending in the direction ofits length, and arranged adjacent to the opposite ends of the slot arebearing rollers 38 and 39. This rear or free end portion of theconnecting rod inclines slightly downward and the slot 37 is ofsutlicient size to receive the lever, so that when the parts are in thepositions just stated, the rollers 38 and 39 will bear on the junctureof the arms 25 and 26. It will be evident now when the cross bar israised in the manner before described that the connecting rod 32 willlikewise ascend and by virtue of the position of the short arm 25 thisascending movement of the connecting rod will rock the lever, wherebythe said short arm will be turned to a substantially vertical positionand the opposite or longer arm moved outwardly thus moving the sleeve tothe outer end of the arm 16.

Having now described the mechanism for operating the screens, adescription of the latter and their connection with the operating meanswill be given :By reference new to Figs. 1 to linclusive and also "i" to9 inclusive it will be seen that arranged in front of and on theopposite sides of the filling space are the screens. The front screen isdesignated in general by the numeral %0 and includes a frame coveredwith a reticulated body, This frame corresponds in length approximatelyto the distance between the cross bar and table 5 when the cross bar isin lowered position, and in width to the width of the table, orapproximately so. T he middle portion of the upper end of the frame isprovided with a lateral arm t2 having openings for the reception ofscrews by means of which it is fixedly secured to the filling head 14,The upward and rear ward extension of the screen is designated at and islocated to tl e left of the arm l2 and bears on the side of the fillingread. The screen shown to the left in Fig. 3 and also illustrated indetail in Figs. 8 and 8 comprises a frame ll over which is stretched ameshcc body The length of the frame +24: corresponds myproximately tothe space between the upper side of the cross bar and table, when thecross bar is in lowered position, as shown in Fig. 1, and in widthcorresponds to the distance between the yoke and stationary front screen40. The rear side of the frame ll is provided with rearwardly extendinglugs and t7 which b on the adjacent side of the yoke and are securedthereto by screws or other suitable fastening means. The screen shown onthe right in Fig. 3 and also shown in detail in Figs. 7 corresponds inwidth to the screen and T just described and includes a frame 48 overwhich is stretched a meshed body 49. The upper and forward corner ofthis screen is removes, so that when the filling head is lowered, asshown in Fig. 1, an opening will be presented for the reception of thesupply pipe which is tapped into the opening let, whereby movement ofthe screen will not be prevented by the supply pipe. The rear side ofthe screen is provided with lugs 51 and 50 similar to the lugs as and 47which are secured to the adjacent side of the yoke by screws or othersuitable fastening means. lVith this construction, 11. will be manifestwhen the filling head is lowered, that the forward sides of the screenwill be adjacent to the opposite sides of the stationary screen, so thatduring the operation of filling a defective bottle, the fragments ofglass will be prevented from flying outward when the bottle breaks. Asshown in Figs. 7 and 8*, the upper and lower ends of the frames areadjacent to their rear ends offset inwardly as shown at 52 and 53, theseoffsets being sufficient to bring the adjacent ends of the frames intoalineinent with the outer sides of the arms of the yoke for obviousreasons.

From the foregoing description, taken in connection with theaccompanying drawings, it will be evident that l have provided a shieldfor bottling machines which is antomatic in operation and comparativelyin expensive to manufacture and which may be applied to most forms ofbottling machines now in use without the necessity of any expensivealterations to the machine.
